This invention relates tol machines for beating eggs, whipping lar uses in connection with the manufacture of candy, pastry, and the like, and provides a construction wherein the beating takes place in a continuous process, the material to be beaten being continuously supplied lat one part 0f the machinerand continuously reinoved'- in beaten and aerated condition at another. j

, In general the machine comprises a tube arranged at an inclination to the horizontal and having therein an agitating member so formed as to tend to feed the material being beaten upwardlyk lengthwise ofthe tube. ProvisiOn is also made for introducing the material to be beaten at the lower end ofthe tube and for permitting thev beaten material kto pass out adjacent to the opposite end,and means is also provided whereby a'current of air is introduced at the lower end ofthe tube, this current of air acting to aid in the beating operation, and passing in the direction of transportation ofthe material as it is being' beaten to the upper end lof they tube where' it escapes. This tube is preferably ja'ckete'd so asl to permit heating or coolingl ofthe mate-v rial being beaten as may be kdesirablev in any particular case. -V Y For a more complete understanding of this invention, reference -maybe had tothe ac-Y companyingr drawings in which Y Figure l isa side'elevaton of the machine.

Figure 8 is a detail of a beater element. The machine in general comprises a tube 1 which is supported at its opposite end from 5 pairs of standards 2 andk 3 which may be cream and for simi` j relative to the standards 3 may be provided Figure 4 is a similar vview of the oppositeV they are formed as loops 'of wire,

`metal having blower vanes 31 formed by slitfixed toa table top or other 'suitable surface. rhe standards 2 have hinged to their upper ends a member 23 having an opening 4 at its upper end to receive one end of the tube'l. The brackets 3 carry vertical adjustment, a member 5 which is formed at its upper end `with a cap portion 6 shaped at 7;' to take over the opposite end of the tube 1. Adjustment of themember 5 by any suitable construction, but as herein shown there are a plurality ofspaced per-v forations 8 in the standards through any selectedone or more of which may be passed securing bolts 9 engaging in suitable holes in the memberV 5. i

' Positioned axially within the tube 1 is a beater member comprisinga central shaft 10, its upper vend as shown being reducedas y y at 11 and journaled in a bearing 12 positioned T within the outer end portion of the lcap portion 6. This bearing as shown is enclosed by `a thimble 13V having threaded engagement with the Vouter end portion of the cap. Near itsk opposite end the shaft 10 is journaled 'in a similar bearing 14 in the end of la cap V15, theflarger end of whichis seated in an annular recess 16 in the member 23 and which is lshown as fixed in position therein by means of thescrews 17.V A thimble 18 is alsopro- 80 vided for enclosing the bearing 14. At this end of the lshaft also isVv positioned a belt pulley 19 fixed. to the shaft by any suitable means'suchasthe set screw 20. This shaft lO'carries beater elements25 arranged in S5 spiral series from adjacent to the lower end of the .tube toward its opposite end and beyond van opening 24 in its lower face through whichY the beatenY material escapes as will later'appear. Y Y Y These beater elementsV may be variously constructed, but as shown best in Figure 8 the vends thereof being fixed as by soldering as at 26 in perforations in the shaft. Between the lower ends of the series of beater elements and the cap 15`is positioned a blowing ele# ment vor fan 80, this being shown detached in Figure 6. This may; be vformed of, sheet ill with capability l ofV t5 ting inwardly from the circumference of a disk as at 32 and twisting the portions 33 between the slits to form the vanes. This disk may be fixed to a hub element 34 which in turn may be liXed to the shaft l0 as by means of a set screw 35.

At 40 is shown a funnel extending through the upper wall of the tube 1 vadjacent to its lower end, this funnel being for the purpose of receiving the material to be beaten which may conveniently be supplied thereto from a sto-rage tanlr 41 positioned above the funnel and provided with a valved outlet 42 at its lower end by which its rate of supplyY may be regulated.

lt is also desirable that provision be made for controlling the temperature of the material being beaten and for this purpose the tube l is shown as provi-ded with a j aciret ezitending throughout the greater portion of its length, this jacket as shown being formed by means of an outer tube 45 arranged concentrically with the tube 1 and surrounding this tube and spaced therefrom adjacent to its ends by means of the ring members 4G. At 47 and 48 are shown pipe connections with the space between the tubes l and 45 through which a cooling or heating' lluid may be passed, for example, cold water or steam.

ln order to stiften the mechanism, 'ie rods, as shown at 50, may be passed through the members 3 and 5 externally of the tubes 1 and 45 and these may also be ext-ended through perforations through one or more rings 52 surrounding the tube 45 between its ends. As shown in Figure 7 these tie rods 50 may be fixed to the rings 52 as by means of the set screws 53.

ln operation the material to be beaten is supplied through the funnel 40 and the shaft carrying the beater element 25 is rotated in such a direction as to'ten'd to convey the ma terial as it is beaten upwardly through the tube toward the exit opening 24. At the same time the fan 30 draws air through openings 55 in the upper portion of the cap 15, the air passing through the `tube in the same direction as the feeding'action of the spirally positioned beating elements. This combined ac tion of the beater elements and fan causes the material as it becomes beaten and .stilfened to be separated from the unbeaten or partially liquid material in the lower end portion of the tube 1 and while continuing its beating and aerating transports this material to the upper end of the tube where it is discharged through the opening 24. lVhile the 'degree of inclination of the tube may be varied to suit the particular material being beaten, in general it is found that the greater th-e inclina tion the stiller the material is beaten up by the time it is discharged from its upper end. This inclination ofthe beater also insures that only the beaten up material will be ejected from the upper end so that there is no danger of unbeaten or insuiliciently beaten material passing out at this point.

ln order to prevent the beaten material from passing upwardly into the cap 6, a plate may be used to close olf the upper end of the tube, this plate having a perforation for the passage of the shaft 10, and in some cas-es it is found desirable to entend from the opening' C guiding member about which the beaten material will flow as it is being ejected. A convenient construction of such a member is shown in Figure 4, comprising a wire bent centrally to form a depending portion within .the area of the discharge opening and having at its upper end oppositely extending portions 5G which may be engaged in any ble manner with the tube 1. In some also it may be desirable to form a tubular extension 68 through which the material is passed from the opening 24.

lt is found that this mechanism is capable of handling materials which is difficult to handle 'with beaters as heretofore commonly made and since the process is a continuous c, the beaten material may be used as it e` from the opening 24 at once without re quiiing the transporting of a volume of the beaten material from one container to another as is necessary where batch processes are employed. This delay occasioned by beating the material in batches often permits the beaten material to revert to its unbeaten condition, thus impairing the quality of the product to be made therefrom and it often results in unor incompletely beaten material being removed with the beaten material. Vil here the beating is continuous and the material is continuously fed out from the ma chineg as is done by the present machine, there is no tendency for the material to revert since it can be used immediately after issuing and is not required to be specially handled before being used and no unor ncompletely beaten material passes out with the beatenmaterial. One of the materials which it has been found possible to beat up very satisfactory in this manner and which it has been found difficult to properly handle with batch beaters is what known dried beef serum which comprises primarily the white corpuscles vof beef blood. The use of this material for confectionery and bakery purposes is becoming of increasing importance. VJ hen this material is beaten up it is usually desirable to pass cold water through the aclret ofthe machine.

lVhen it is desired to clean the machine it is only necessary to remove the screws 17 which hold the cap 15 in position, whereupon the beating elements and fan with the shaft on which they are fixed may be removed bodily from the tube, the reduced end 11 at the upper end of the shaft permitting this end to be detached from its bearing by en'dwise movement. An annular shoulder 70 on the shaft tion relative to the horizontal,

bearing against the inner face of the bearing 14 in the cap 15 Vacts to hold the shaft in proper endwise position when the cap 15 is fixed to the member 3. Y
